Introducing our CNC-machined 6061 aluminum hose adapter with multiple ports! With this adapter, you can house two independent fan controller temperature sending units and a coolant temperature gauge sending unit.

Set up two automatic fan controllers to turn on at different temperatures. One fan can serve as your primary while cruising on the highway, and the second fan can turn on when temps start to rise. 

Check out our SPAL fan combos, Koyo performance radiators, and performance fan shrouds to get the ultimate cooling setup. We've done all the hard work of choosing the best cooling products available so you can rest assured that cooling issues will be a thing of the past.

Easy Install: Replace a 1" straight section of your lower radiator hose with our hose adapter by cutting and removing it. Use the included hose clamps to secure it in place. You can choose from any of the three holes provided to connect your sending units to a clean and precise coolant stream.
